Fatal Python Error on Startup (Not Responding)
That looks like Blender is using a very old version of Python. Try taking any path in C:\Python27 off your PATH environment variable.

I'm assuming you're running Windows 10, since you clearly use Windows but don't mention which version. Right-click on "This PC", then choose "Properties". In the next screen, click "Advanced System Settings", then click on "Environment Variables". In both the box "User variables for {your name}" and "System variables" doubleclick on "Path" (or any other capitalisation) and remove anything that starts with C:\Python27.

You may want to write down the original values you removed, just so you can restore them later.
